CB Zack Bowman says to keep an eye on his former Nebraska teammate Ndamukong Suh

Bears cornerback Zack Bowman works out with Detroit Lions defensive tackle Ndamukong Suh, because the two were college teammates at Nebraska.

But Bowman said Suh has gotten progressively more aggressive over the years and added that the Bears need to “keep an eye out” on him.

“I wish I was out there. I would get into Suh’s face for Jay [Cutler],” Bowman said. “We got to keep an eye out on him [Suh] because he will do something nasty – not like disgusting – but cheap shot, cheap hit, because he is kind of known for that.”

Asked if Suh is a dirty player, Bowman said, “That’s his attitude, that’s his mentality.

“Obviously, that’s the type of player he wants to be in this league. He has a reputation for it, and it fits him well. And if it ain’t broke, why fix it. And some teams do fear him.”

Bowman said Suh started to develop that reputation in his junior and senior seasons at Nebraska.

“You could start to see it,” Bowman said, “and now it’s out of control.”

But Bowman said Suh isn’t always the same person.

“Off the field, he’s nice. He does a lot of charity work,” Bowman said. “But on the field, he turns into the Hulk.

“It’s like two different people.”

In Suh’s first year at Nebraska, Bowman recalled walking in a parking lot and watching the defensive tackle picking up a car, about the size of a Toyota Prius.

Asked what he was thinking, Bowman said, “Beast.

“I’ve never seen that before.”

In a conference call Thursday, Suh defending his mindset.

“I honestly don’t have a concern of whether people think I may cross it or now. I’ve said it many, many times and I’ll say it again. I don’t teeter-totter around that line,” he said. “I feel that I play very hard and aggressive and that’s how I got where I am today, playing blue-collar football and being physical, and doing them with a hard nose. I think it’s one of the reasons I’m successful. People are entitled to their opinion.”
